Please excuse the terminalogy as I am not
an optical engineer.
I seem to recall hearing about devices that
could detect a tap in fiber. They worked by
sending light at frequencies slightly different
than the primary channel. If the fiber were
bent to tap the light, the other frequencies
would attenuate a larger amount than the
primary channel thus allowing a monitor
to "see" the tap.
Any body else hear of these things?
